(a)

Interpretation Introduction

Interpretation: The value of Kp at 900°C for the decomposition reaction of CaCO3 is given. If the initial amount of calcium oxide increase, decrease, or remain the same is to be stated in each case.

Concept introduction: Reaction quotient, Qp , is the measure of concentration or partial pressure of reactants and products of a system before equilibrium point is reached.

The direction of reaction depends on Qp and Kp ,

• If Qp>Kp , the reaction shift to the left.
• If Qp<Kp , the reaction shift to the right.
• If Qp=Kp , the reaction will reach the equilibrium.

To determine: If the initial amount of calcium oxide increase, decrease, or remain the same for the given values.

### Explanation of Solution

Explanation

The initial amount of calcium oxide decreases as the value of Qp is greater than Kp .

Given

Mass of CaO is 1.00g .

Partial pressure of CO2 (PCO2) is 2.55atm .

The value of Kp at 900°C is 1.04
